Yes, allowing for ownership verification is high on the list of new features we plan to roll out later this year.
We’ll have a major update to the storefront experience later this year that will include the new system for ratings and reviews, but it’s still several months from release. We’ll have more information in the coming months as we get closer to the release.
If the seller isn’t responding to you and the product isn’t working, feel free to contact us with the issue here. If the seller isn’t supporting a broken product, we can remind them of their obligation, and we can look at providing you with a refund.
